摘要

Ten 2-cyclopropyl-1-and-2-alkenes have been prepared from methyl cyclopropyl ketone by condensing the ketone with various Grignard reagents and dehydrating the resultant methylalkylcyclopropylcarbinols. Both alumina at 200 to 250 O and sulfuric acid were found to be satisfactory dehydrating agents. Isolation of both the position and geometrical 2- cyclopropylalkene isomers in high purity was accomplished by fractional and azeotropic ...
